The machine itself controls most of the variables, thus repeatability and reproducibility are consistent. ASTM G65-04(2010) “Standard Test Method for Measuring Abrasion Using the Dry Sand/Rubber Wheel Apparatus”. Figure 1. ASTM G65 is a standardized wear test during which an abrasive material (purified silica sand) is.
